SASH-FASTENER.

SPECIFICATION forming part or Letters Patent No. 548,695, dated octobere9, 1895.

Application filed June 20, 1895.

To all whom it may concern.:

Be it known that I, HENRY E. CAPRON, a citizen of the United States,residing at Pinkhamton, in the county of Larimer and State 5 ofColorado, have invented certain new and useful Improvements inWindow-Fasteners; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which itappertains to make and use thesame.A

My invention relates to improvements in devices ,for raising andlowering windowsashes, the object of the same being to provide simplemechanism to be operated by hand whereby the window-sashes may be raisedor lowered and adjusted and locked in any desired position. Y

The invention consists of a window-frame having suitable recesses orgroovesV for the reception of the sashes and a casing formed below thesashes, in which a part of the operative mechanism of mydevice islocated.V Both sashes are provided with extensions upon their lowerouter sides, and the outer edges of said sashes have secured to themrack-bars, which engage pinions upon the outer end of a pair oftransverse shafts mounted in suitable bearings in the casing below thewindowframe, which shafts are actuated through cogwheels whose centralshafts project out through thel casing, and provided with handles on theouterends thereof, which handles are adapted to be bent over at theirpoints of connection with the shafts of the cog-wheels, so that theirprojecting end may be inserted in slots or openings in the outside ofsaid casing. l

The invention is clearly illustrated in the accompanying drawings,in'which Figure 1 represents a front elevation of my device shownapplied. Fig. 2 is a similar View of the same with the front of thecasing removed. Fig. 3 is a vertical section on the line x of Fig. 2.Figs. 4and 5 are detail perspective views. Y Like reference-numeralsindicate like parts in the various views. Y

The window-frame 1 is of the usual form of 5o construction, except ashereinafter described. Below the window-frame is formed a casing`rack-'bars 9 on the outer Serial No. 553,436. (No model.)

in which is located part of the operating mechanism of my device. Thesaid casing has a removable cover 2, formed with metallic disks orplates 3 3 thereon, each of which is 55 provided with a series ofperforations 4 4, as clearly shown in Figs. 1 and 4. On the inside ofthe cover 2, within the said casin g, is mounted in suitable bearings apair of parallel shafts 5 and 6, the shaft 5 having pinions 7 on its 6oouter ends Vand the shaft 6 being provided with similar pinions 8 uponits ends. The pinions 7 7 mesh with rack-bars 9 9 upon the extensions 1010 of the upper sash 1l, and the pinions 8 8 mesh with similar rack-bars12 12 65 upon the extensions 13 13 of the lower sash 14. The sashes 11and 14 lit the frame 1 in the usual manner, and the extensions 10 and 13thereon project downwardly in the casing below said window-frame. Theshaft 5 is fur- 7o ther provided with pinions 15, which may be integralwith the pinions 7, which are engaged by a cog-wheel 16 on the inner endof an operating-shaft 17, as clearly shown in Fig. 4. The shaft 17 ofthe cog-wheel16 projects outwardly through an opening in the cover 2 andone of the plates or disks 3 thereon. Similar operating mechanism isconnected with the shaft 6. Pivotally connected to the outer end of theshaft 17 is handle-bar 18, havinga han- 8o dle 19 upon its outer end.Surrounding' the shaft 17 is a coiled spring 20, which, acting againstthe squared end of the handle-bar, tends to hold the same in any one ofits adjustedV positions. 8 5

The operation of but one sash will bedescribed, as both sashes areactuated in the same manner. The window-sash 11 beingin its upperposition, by turning the handle-bar 18 the cog-wheel 16 is rotated, andthrough it 9e and the pinions l5 the shaft 5 is turned in its bearings.,The pinions 7 upon the outer ends ofthe shaft 5, acting in engagementwith the. ends of the sash 11, force said sash downwardly. When thedesired 'height has been reached, the handlebar 18 is turnedv upon itspivotal connection with the shaft 17, so that the handle proper 19 fitsone of the perforations4 in the disk 3. The window isthereby securelyheld in place..` roo A reverse action to that just described will raisethe sash 11.

Having thus described the invention, what is claimed as new isf- Thecombination with a window frame having a casing below the same, whosecoveris provided with disks each having a series of perforatons therein,of an upper and lower Window sash each having extentions from its outeredges, rack bars thereon, a pair of parallel shafts mounted in suitablebearings in said casing each provided with pinions at its ends whichengage the teeth of the racks, on the upper and lower sashesrespectively, a pair of cog wheels engaging the pinions on said shafts,respectively, a handle bar pivot-
